Letters Patent No. 112,150,l dated February 28,1871.

IMPRVEMENT IN ANIMAL-PQKES.

The Schedule referred to in these Letters Patent and making part of the same.

To whom it 'may concern:

Be it known that I, LEWIS KELLEY, of Saranac, in the eountyof Ionia and State of Michigan, have invented a new and useful Improvement in Animal- Pokes; and I do declare that the following is a true and accurate description thereof, reference being had to the accompanying drawingr and to the letters of reference marked thereon and being a part of this specication, in which- Figure 1 is a perspective, and

Figure 2 isa plan of the poke, springs, andneedles.

Like letters indicate like parts in each figure.

The nature of this invention relates to au improvement in the construction of that class of implements employed to prevent horses and cattle from jumping or from pushing against fences, and is designed as au improvement upon the invention for which Letters Patent were granted to William Kelley, July 1.9, 1870.

It consists in the arrangement of its several parts, all constructed as more fully hereinafter described.

A represents a yoke, which is of the ordinary form and construction, the lower ends of which are secured in co-relation to each other by the rod or bolt B.

Gis arock-shaft, journaledinto the sides of the yoke, as shown. To this shaft is rigidly fastened the poke or lever D.

. E is a bell-crank, pivoted by means of the bolta to the under side of the lever.

F is a C-spring, one end of which is secured to the v under side of the lever, while the other end is securedto the lower end of'the bell-crank. There are two of these bell-cranks, one upon each side of the lever, and connected together by the bolt b, to which the end of the C-spring is fastened.

G are needles, pivoted to the upper ends of the bellcranks, and projecting through suitable holes h in the rock-shaft in such a manner that they do not protrude through said holes when there is no pressure upon the lever. "When there is such pressure, the needles .protrude and prick the animal, and when he retires the C-spring impinging againstthe lever and the rod or boltl B withdraws the needles.

What I claim as my invention, and desireto secure by Letters Patent, isf' The arrangement of' the rock-shaft C, bell-crank E, spring F, needles G, and lever D, with the yoke A, when the several parts are constructed and operated substantially as described and shown, for the purposes set forth.

LEWIS KELLEY.
